a44e9afdd1 FORTIFY_SOURCE: optimize 
Don't do the fortify_source checks if we can determine, at
compile time, that the provided operation is safe.

This avoids silliness like calling fortify source on things like:

  size_t len = strlen("asdf");
  printf("%d\n", len);

and allows the compiler to optimize this code to:

  printf("%d\n", 4);

Defer to gcc's builtin functions instead of pointing our code
to the libc implementation.

d89ce40d8e linker: add -Wl,--exclude-libs,ALL to LDFLAGS 
The linker is essentially a shared library, and incorporates
it's own copy of libc. Even though it's unnecessary, currently
/system/bin/linker is exporting various libc symbols (only to
apps which explicitly dlopen /system/bin/linker)

Add --exclude-libs,ALL, which tells the static linker to mark
all of the imported libc symbols as hidden. This reduces the
size of /system/bin/linker from 92K to 67K with no obvious
loss in functionality.

  $ adb shell ls -l /system/bin/linker
  -rwxrwxrwx root     root        92260 2013-01-16 16:52 linker

  $ adb shell ls -l /system/bin/linker
  -rwxrwxrwx root     root        67660 2013-01-16 16:49 linker

Documentation on exclude-libs can be found at

36bd371e26 Revert "stack protector: use AT_RANDOM" 
The AT_RANDOM changes broke setuid / setgid executables
such as "ping". When the linker executes a setuid program,
it cleans the environment, removing any invalid environment
entries, and adding "NULL"s to the end of the environment
array for each removed variable. Later on, we try to determine
the location of the aux environment variable, and get tripped
up by these extra NULLs.

Reverting this patch will get setuid executables working again,
but getauxval() is still broken for setuid programs because of
this bug.

This reverts commit e3a49a8661.

e3a49a8661 stack protector: use AT_RANDOM 
Populate the stack canaries from the kernel supplied
AT_RANDOM value, which doesn't involve any system calls.
This is slightly faster (6 fewer syscalls) and avoids
unnecessarily reading /dev/urandom, which depletes entropy.

faa0fdb119 arm syscall : for eabi call_default don't use stack 
In the default case, we don't need to use the stack, we can save r7 with
ip register (that what does eglibc).

This allow to fix vfork data corruption
(see 3884bfe966), because vfork now don't
use the stack.

a0f64756a4 Filter ANDROID_PROPERTY_WORKSPACE 
When executing a setuid executable, filter out ANDROID_PROPERTY_WORKSPACE
from the environment. Some applications implicitly trust the property
space and don't realize that it's passed by an environment variable
which can be modified by the caller.
